In most Western countries there is a widespread belief, fostered in part by historical prejudice and religious proscription, that inbreeding in human populations causes a reduction in fertility. Support for this belief has been claimed in HLA-based studies, with increased rates of fetal losses suggested in HLA-compatible unions. To critically assess the overall status of fertility in consanguineous unions, data on 30 populations resident in six countries were collated from a systematic review… Expand
Consanguinity, human evolution, and complex diseases
TLDR
A range of primarily social factors, including urbanization, improved female education, and smaller family sizes indicate that the global prevalence of consanguineous unions will decline, which will initially result in decreased homozygosity, accompanied by a reduction in the expression of recessive single-gene disorders. Expand
Impact of inbreeding on fertility in a pre-industrial population
TLDR
It is suggested that inbreeding depression affects reproduction in modern societies through an interaction with age, as compared with the first half of their reproductive period. Expand
INBREEDING PATTERN AND REPRODUCTIVE SUCCESS IN A RURAL COMMUNITY FROM GALICIA (SPAIN)
  • V. Fuster
  • Medicine, Biology
  • Journal of Biosocial Science
  • 2002
TLDR
Information from 1503 reconstituted families shows that complete fertility was slightly higher among consanguineous families despite a greater infant mortality, which could explain the above results. Expand
Consanguinity and the Developmental Origins of Health and Disease
TLDR
It is proposed that close kin unions may maximize current reproduction while minimizing reductions in offspring reproductive value under conditions of chronic intergenerational poverty and inequality. Expand
Reproductive pattern in consanguineous and non-consanguineous marriages in La Cabrera, Spain
TLDR
In the La Cabrera population, consanguinity appears as a socio-cultural process that affects the reproductive dynamic and modifies the marital structure and alters the reproductive pattern, prolonging the reproductive period, which results in a greater number of offspring. Expand
Consanguineous marriage and human evolution.
TLDR
This work has indicated that the shift from consanguineous marriage to panmixia has been accompanied by a reduction in homozygosity, and predicted decrease in incidence of both recessive single-gene disorders and more common adult-onset diseases. Expand
Associations of autozygosity with a broad range of human phenotypes
TLDR
The authors show that a genomic inbreeding coefficient (FROH) is associated with disadvantageous outcomes in 32 out of 100 traits tested, suggesting that genetic variants associated with inbreeding depression are predominantly rare. Expand
Consanguinity and child health
TLDR
Given the recent patterns of immigration, many Western countries have continued exposure to consanguineous unions, which necessitates the provision of more focused resources to improve the delivery of prospective genetic counselling, prenatal testing, treatment and community care. Expand
Consanguineous marriage and childhood health

  • Developmental medicine and child neurology
  • 2003
TLDR
The aims of this annotation are to review briefly the current global prevalence of consanguineous marriage and to estimate and describe the deleterious outcomes expressed in the early years of life. Expand
Assessment of association between consanguinity and fertility in Asian populations.
TLDR
The association between consanguinity and fertility was assessed reviewing published literature and analyzing demographic and health survey data from Pakistan and India, showing higher fertility among women in the first-cousin unions compared to those married to non-relatives. Expand

The effect of parental consanguinity and inbreeding in Hirado, Japan
TLDR
It is suggested that on Hirado the increased reproductivity of the consanguineous marriage largely offsets the increased mortality among the issue from such unions, and thereby dampens the rate of elimination of deleterious genes and the loss of genetic variability. Expand

TLDR
The effects of inbreeding on fertility among inbred adult Hutterites is investigated and significantly reduced fecundity among the most inbred Hutterite women, as evidenced by longer interbirth intervals and longer intervals to a recognized pregnancy, which suggest the presence of recessive alleles that adversely affect fertility among the population.

Consanguinity as a determinant of reproductive behaviour and mortality in Pakistan.
TLDR
Unions between close biological relatives were characterized by younger maternal and paternal ages at marriage and reduced spousal age difference, but a longer time to first delivery, but overall, they exhibited greater fertility than non-consanguineous couples. Expand

TLDR
The average B value and the number of lethal equivalents found for the highly inbred southern Indian populations in general and for the Vadde in particular were much smaller than those from other parts of the world, providing empirical support to Sanghvi's hypothesis on long-term effects of inbreeding.

The effect of consanguineous marriages on reproductive wastage
TLDR
No consistent increase in reproductive wastage was evident as the inbreeding coefficient, F, advances mainly because of decline in the wastage rate among the double first cousin marriages which represents only 2% of the sample. Expand
